plexiform cellular schwannoma

Thursday 7 May 2009

Plexiform nerve sheath tumor of childhood had been previously designated a form of malignant peripheral nerve sheath tumor (MPNST). These tumors are in fact benign plexiform cellular schwannomas.

The behavior is that of a benign tumor, although its often rapid growth, hypercellularity and increased mitotic activity, sometimes locally aggressive behavior, and difficulties encountered in obtaining tumor-free margins are unsettling to pathologist and clinician alike. These features may lead to a misdiagnosis of malignancy, which could result in harmful overtreatment. (14508393)
